To" all "echo/n concern Be it known that I, ALBIN R.

Moline, in the county of Rock Island and State of Illinois, have invented certain new and useful Improvements in Air-Guns, of which the following is a specification.

This invention relates to air guns. or pistols, and belongs to that class ofv weapons designed to propel projectiles by means of compressed air, and containing anV air compression chamber in which a plunger is drawn by hand in one direction against the forceof Va spring until caught and held by a trigger device whereby the plunger may be released'at will to compress the air.

In this invention the object is to produce an air gun of therclass stated, having the compression chamber and the barrel and bore of the gun arranged parallel with each other, the bore and chamber having openingsin the same plane which are suitably connected `by means of a pivotal breech block, in one position of which theopeiiing into the bore is uncovered for the introduction of the projectile. The special construction l and arrangement of the various parts is likewise an object of this invention, as it is believedV that such arrangement results in a particularly compact, easily understood andV operated device, not liable to get out of order l Vand especially cheap to manufacturers.

The accompanying drawings illustrate Y the special construction and arrangement of Y piece.

the parts of this invention, and Figure `1 represents a rear view showing the peculiar form and disposition of the breech block pivotally carried upon the breech of the Fig. 2 is a vertical section lengthwise of the air chamber and barrel of the gun, taken upon the indirect broken line 2-2 of Fig. 1 and showing all parts assembled. Fig. 3 is the breech block face.

. Throughout the drawings and description` the same letter is employed to refer to the same part.

Considering the drawings, which set forth this invention in the form of a pistol, A

` f isI the body and a the handle or grip. The

body comprises two parallel features, one being the air compression chamber B, and the other and upper portion being the barrel b having the usual bore for directing the projectile. The compression chamber is closed at thek outer end byl the screw cap C,

' and the mouth of the bore' of the barrel is .psiially screw-threaded as'` inpractice v F ALK, a citizen of the United States, residing atv in order that an extension of the barrel may be attached if desired at any time.

The trigger D acts upon a slide d against the force of a spring E, and the upper wedge-shaped end e of the slide is arranged to catch the edge of a plunger F in the compression chamber, @when Ithe plunger is drawn outwardly by the iod f against the force of the coil spring G, by the hand grasping the external eye or finger piece g.

When the plunger is released the airis forced out through the discharge port H which opens into the compression chamber1 B. From the discharge port the air passes into the groove hin the facel of the breech Vblock J. The groove is formed with closed ends, as best shown in Fig. 3, and it is constructed to connect the discharge port H of the compression chamber, and the rear opening or end of the bore of the barrel. The breech block J is pivotally supported and clamped upon the end of the body A -by the thumbscrew j, which passes throu h the block to one side of the groove 7L'. t will be `observed that the mouths of the discharge port H and of the rear end of the barrel o lie the same plane, which is the plane of the rear of the body A, and against which the face of the breechblock rests. In Fig. l is shown the spring K on top of the barrel and the pin Ze beneath the end of the spring and extending into the barrel in the path of the projectile L, the purpose .of the spring pin being to prevent the projectile from falling out of the bore if the muzzle of the pistol is lowered.

In operation, the thumbscrew y' and the top of the breech block' are turned to the right, which uncovers the open end of the bore of the barrel for the introduction of the projectile L. The block and thumbscrew are then turned backv which clamps the block in place with the groove 7L connecting the discharge port H and the bore of the barrel. If the plunger is now operated the compressed airwill rush into the bore by way of the breech block and drive the projectile out of the bore with great force and accuracy.

Having now described this invention, and explained the mode of its operation, what I claim is':

1. In an air gun, the combination with: a compression chamber andl av barrel having rea-r openings in the sain'e plane; of abreech block pivotallysupported e and movable transversely upon the rear end of said barrel and compression chamber, and the `said block having a groove arranged tp'oonneot said openings of the barrel and chamber. g'

compression oharnber and barrel v,having openings nwthe s'ame'plane, of a breech C opies of this patent may be obtained for `hlookpvotally l supported hand movable transversely upon the rear ends of said barrel and compression chamber, a thumbsorew tor clamping sald block 1nY place, and the Y l lsaid block having a groove arranged to con- 2. In an air gun, the comblnatlon with aV neet said openings of the barrel and chamber. Iii-testimony whereof I ax my signature.
